IMPROVED WEATHER-STRIP fiilgt snout rennet it inflgm 3mm fitment amt mating'ynrtnf flgt smite.

Be it known that I, WASHINGTON L. GILROY, of the city of Philadelphia, in the State of Pennsylvania, have invented a. new and useful Improvement in the Construction 'of Weather-Strips composed of wooden mouldings, or their equivalent, and India. rubber, or its equivalent, for windows, doors, &c.; and Ido hereby declare and ascertain said improvementas follows:

Figure 1 representing a front view of the wcather-strip. V

Figure 2, a transverse sectional view in the accompanying drawing.

A In weather-strips made before these improvements of mine, the elastic material has been inserted in one of two ways, namely, perpendicular to theface of the wooden moulding, or in a loop or tube-form. These are well known, and we need not, therefore, more particularlydescribe them.

These modes of construction having serious objections to urge against them in practical use, my first improvement is to obviate them, which it most effectually docs. My second improvement is in the mode of fustei'iing the elastic medium into its wooden matrix by means of cement, instead of tacking, as has always before been done, and which is peculiarly objectionable in the slender light strips most desirable for this pur-.

ose. Instead of inserting my flat, straight elastic strips into the wood, at right angles theretoyas above remarked, I insert the same at an angle of forty-five degrees, more or less, so that the portion that projects beyond the surface of the strip acts as an elastic, readily-yielding spring that will fit surfaces that are quite unequal, and the strips themselves need not be so accurately cut or inserted to be more effective than those that do not incline. i 7

There is an inclined saw-kerf, or narrow, deep groove cut into the wooden strip A at w, and the India. rubber, B, is put therein with water-proof cement. It will be noticed that the light slim moulding would be weakened by this groove 01, and that if the rubber were pinned or nailed into it, the moulding would be still more weakened; I therefore use thecement for the double purpose of more effectually uniting the rubber B and moulding A, but also as strengthening and solidifying the moulding.

Having thus fully described my improved construction of weather-strips, composed of rigid strips-of wood and elastic medium, whiit I claim therein as my new improvement, is-

1. The insertion of a flat elastic strip into a moulding, such as above described, in an inclined position to its surface, as herein set forth.

2. I also claim afiixiug said elastic medium into the groove in the rigid moulding by means of water-proof cement, as and fertile purposes specified.
